This item was purchased at a tableware exhibition held at the Tokyo Dome a few years ago. I've lost the instructions, so I don't have all the details, but I remember the shop assistant saying it was from an Echizen-nuri shop. I apologize if that's incorrect. I've used it a few times, but my family has become smaller and our lifestyle has changed, so I'm putting it up for sale. The size is just right, it fits comfortably in the hand, and it enhances the flavor of food. Thank you very much. Size: Ochoko (sake cup) 8x6.5cm : Yakumi-ire (condiment dish) 8x1cm
